Abstract: A dental observation device by which, without displaying, in an overlapping manner, a visible light image of an image-capturing site in an oral cavity captured by a 3-D camera and 3-D image information on the image-capturing site in the oral cavity acquired in advance, an invisible portion in the visible light image is easily recognized.
An observation system includes a visible light 3-D camera; a relative position calculator; a 3-D information storage storing 3-D image information acquired in advance; an image display displaying, side by side, a 2-D captured image captured by the visible light 3-D camera and 2-D converted image based on the 3-D image information corresponding to the surgical operation target site; and a display direction adjuster displaying, in the image display, the 2-D converted image in a predetermined direction on the basis of the image-capturing direction detected by the relative position calculator.

Abstract: A learning model provided in a segmentation device is a learning model which is generated using training data such that segmentation data of a feature region is output when at least one of projection data and reconfiguration data acquired by an imaging device or data derived from the at least one of projection data and reconfiguration data is input.
